99 S80 T6 Vaccum hoses

[AuroraTear]

Hi. I have 2 other posts here so I have had nothing but trouble. My Brake booster has a bad seal and makes a Wooshing sound occasionally when i let off of it, WHen i tap it quickly it seals up na dstops. I know its a vaccum leak and I already have another Brake booster to replace it with. I have a surging its sporadic now, slight shaking and studdering in the engine and power acceleration at times (feels like i dont have turbos) it sounds like I have a vaccum leak in the dash board too on the passengers side I can hear a slight sucking when i accelerate. Im looking for a diagram or someone that tell me where all my vaccun lines are on this car.. and I mean all of them. Ill replace every single one.

Car has had a Head gasket replaced
timing belt kit,
oil change (penzoil platinum)
spark plugs,
air cleaner
Bank 2 sensor 1 O2 sensor
all in the last 1000 miles

I do belive my final problem with this car is a simple vaccum leak ive had since I got it. Please help me. i think this will be the cheapest thing yet
